And now about some Christmas carols....

The words and lyrics of the old
Christmas carol 'Joy to the World' were written in 1719 by Isaac Watts
(1674-1748). 'Joy to the World' is a popular Christmas carol which is
based on Psalm 98 in the Bible.

'Away in a Manger' is always the first
carol that children are taught. Away in a Manger was originally
published in 1885. The publication of 'Away in a Manger' was in a Lutheran
Sunday school book and this created the misconception that the lyrics
of 'Away in a Manger' were actually written by Martin Luther himself. The
real author is unknown.

Rector Phillips Brooks (1835-1903) of
Philadelphia, wrote the words to 'O Little Town of Bethlehem' in 1868,
following a pilgrimage to the Holy Land. He was inspired by the view of
Bethlehem from the hills of Palestine especially at night time hence the
lyrics of 'O Little Town of Bethlehem'. His church organist Lewis Redner
(1831-1908) wrote the melody to 'O Little Town of Bethlehem' for the
Sunday school children's choir.
